PHP XML RPC Parse Method Descriptions

PHP Version: (PHP 4 >= 4.1.0, PHP 5)

Description

This function decodes the xml into a set of method description.

Usage:

array xmlrpc_parse_method_descriptions ( string xml)

This function decodes the xml into a set of method description. The main objective of this function is to convert the request xml into a list of method description so that you can call appropriate method during server processing.

PHP Code:

This is the server code:

<?php

//This method will be invoked by the server.

function dummyresponse($method, $params) {

switch($params[0]) {

case 'test1':

$reply = 'Your request string contains test1.';

break;

case 'test2':

$reply = 'Your request string contains test2.';

break;

default:

$reply = 'You have requested with no parameters';

}

return $reply;

}

//create a server

$server = xmlrpc_server_create();

//register the 'dummyserver' name as external name and then the 'dummyresponse' name is the actual

//function name.

xmlrpc_server_register_method($server, "dummyserver", "dummyresponse");

//get the request.

$request = $HTTP_RAW_POST_DATA;

//decode the xml into a set of method description

$arr = xmlrpc_parse_method_descriptions($request);

//find the method name

$methodName = $arr['methodName'];

//print the method name

print "Method Name :".$methodName;

//the parameters here are 'server, xml-string and user data'.

$response = xmlrpc_server_call_method($server, $request, null);

//print the response

print $response;

//destroy the server

xmlrpc_server_destroy($server);

?>

The client PHP code is

<?php

functiondo_call($host, $port, $request) {

$fp = fsockopen($host, $port, $errno, $errstr);

$query = "POST /default/php/xmlrpc_parse_method_descriptionsserve.php HTTP/1.0\nUser_Agent: This is a Dummy Client\nHost: ".$host."\nContent-Type: text/xml\nContent-Length: ".strlen($request)."\n\n".$request."\n";

echo '<PRE>';

echo $query;

echo '</PRE>';

if (!fputs($fp, $query, strlen($query))) {

$errstr = "Write error";

return 0;

}

$contents = '';

while (!feof($fp)) {

$contents .=fgets($fp);

}

fclose($fp);

return $contents;

}

$host = 'localhost';

$port = 80;

$request = xmlrpc_encode_request('dummyserver', 'test1');

$response = do_call($host, $port, $request);

//print the response

echo $response;

?>

The method name is as echoed out in server:

Method Name :dummyserver
